Hi,
The problem you have presented would appear to indicate a problem with the on/off switch itself .
This part would be available as a spare part derectly from our Spares Dept or alternatively a service visit could be arranged thorugh our Service Dept - the contact telephone number being 0844 980 0750.
I hope this information is of help.
